chore: Migrate 3 APIs to OwlBot
chore: Migrate 3 APIs to OwlBot

These are:

- Contact Center Insights
- Firestore (underlying API)
- Dialogflow CX

None of these require pre-generation modifications. Firestore
requires a patch to be applied post-generation, but the OwlBot
post-processor already does that.
